The document discusses the IEEE 802 networking standards developed by the Institute of Electrical and Electronics Engineers. It provides specifications for networking technologies, ensuring compatibility for network interfaces and cabling. The IEEE 802 standards predate and are compatible with the OSI networking model. The standards define networking behaviors for the physical elements of networks, including network interface cards, cables, connectors, and media access control.

3.  Institute of Electrical and Electronics
Engineers
 Leading developer of industry and standards
in a broad range of technologies
 Mission: foster technological innovation and
excellence for the benefit of humanity.

4.  provides detailed implementation
specifications for a number of networking
technologies
 Influential set of networking standards
Guide to Networking Essentials, Fifth Edition 4

5.  The IEEE defined a set of LAN standards to
ensure network interface and cabling
compatibility
 Project 802 (inception on February (2) of 1980)
▪ Concentrates on standards that describe a network’s physical
elements
▪ NICs, cables, connectors, signaling technologies, media access
control, and the like
 OSI model was not standardized until 1983–1984
 IEEE 802 standards predate the model
 Both were developed in collaboration and are
compatible with one another

IEEE 802 Specifications (continued)

8.  MediumAccess Control
 collisions
 Data Communications Protocol
 A protocol must also exist for transmitting data
once the node has gained control of the medium
and is able to transmit.

12.  Ethernet
 CSMA/CD – Carrier Sense MultipleAccess
with Collision Detection
 Terminates transmission when it detects collision

13.  Token Bus
 Implementing a token ring protocol on a
coaxial cable
 Used for industrial applications
 Used by General Motors in their MAP
(ManufacturingAutomation Protocol)
 Not reliable

15.  Demand Priority or High Speed Networking
 100Mbps Ethernet standard over Category
3UTP
 Also called 100VG AnyLAN
 Carries both Ethernet andToken Ring
Guide to Networking Essentials, Fifth Edition 15

16.  The OSI reference model and IEEE Project 802
define a frame of reference for networking and
specify the lower-layer behaviors for most
networks
 Together, these models describe the complex
processes and operations involved in sending and
receiving information across a network
 The OSI reference model separates networking
into seven layers, each with its own
purposes/activities
 From the bottom up: Physical, Data Link, Network,
Transport, Session, Presentation, and Application
Guide to Networking Essentials, Fifth Edition 16

17.  Data frames consist of three parts: frame header,
data section, and frame trailer
 Classified as unicast, multicast, or broadcast frames
 The IEEE 802 project elaborates on the functions
of a network’s Physical and Data Link layers by
dividing the Data Link layer into two sublayers:
Logical Link Control (LLC) and Media Access
Control (MAC)
 Together, these sublayers handle media access,
addressing, and control and provide reliable, error-free
delivery of data frames from one computer to another
